DEFINITION

Classification: 315/5.13

(under subclass 5) Subject matter including a magnetron, the hollow device through which the ray passes constituting the resonator of the magnetron.

(1) Note. The subject matter of this subclass usually is a magnetron having an additional cathode projecting a ray through the magnetron resonator for tuning purposes.

SEE OR SEARCH THIS CLASS, SUBCLASS:

5.14+, for a hollow distributed parameter device having a plurality of rays passing through or in.

5.53+, for a hollow distributed parameter device having a ray passing through or in and involving tuning.

39.51, for distributed parameter resonator type magnetrons, and especially subclass 39.57 for such magnetrons with variable tuning by electron emission in or adjacent the resonator space, no means being included to form the emission into a restricted beam or ray.
